In this paper we describe an interactive activity that illustrates simple linear regression. Students collect data and analyze it using simple linear regression techniques taught in an introductory applied statistics course. The activity is extended to illustrate checks for regression assumptions and regression diagnostics taught in an…

Purpose: To explore the use of asynchronous and synchronous text-based communication using the internet as a means of promoting discussion among a knowledge-building community of school students carrying out a science investigation. Design/methodology/approach: Activity theory is used to bring together the various theories associated with the…

For the treatment of disruptive behavior disorders, parent training and child social skills training have established efficacy in research settings. But in community settings, these approaches are not often systematically implemented. In a hospital-affiliated psychology practice located in a rural community, parent and child group programs were…

Many school districts are putting data to good use, although much of the data used in administrative decision making ultimately derives from standardized test scores, which raises a host of other related concerns. The author's purpose in this article is not to critique the types or sources of data that administrators use, but to suggest that there…

Long considered four-letter words by many in education, "data," "testing," and "assessments" have come to signify more than additional burdens and distractions from instruction for most educators. Although many educators are still wary of data, many top-performing school systems have embraced data as a means to drive educational decision making…

In high school, many students do not have an opportunity to learn or use statistics. Because statistics is a powerful tool and many students take a statistics class in college, prior exposure to statistics in a chemistry course (or another course) would benefit students. This paper describes some statistical concepts and tests with their…

Although the process of doing social network analysis (SNA) is similar to traditional research and evaluation design, it is in the details that the two traditions diverge. This article describes two areas of differences: (1) the framework for doing SNA; and (2) data collection, analysis, and specific measures. SNA is about relationships and how to…

This investigation was motivated by observations that when persons with dysarthria increase loudness their speech improves. Some studies have indicated that this improvement may be related to an increase of prosodic variation. Studies have reported an increase of fundamental frequency (F0) variation with increased loudness, but there has been no…

We report on how two middle-grade teachers supported their students' mathematical reasoning within the context of a novel modeling task in data analysis. We examine how the task features supported the development of teachers' knowledge as their students engaged with the task. Analyses of the teachers' practices suggest that the task features…

Despite often brief and superficial coverage in research reports, discussion of the processes through which qualitative data has been analysed in a particular project is an essential part of the recording of the work. A recent PhD thesis examining the information-seeking behaviour of young people described in some detail the procedures in this…

The "Connected Mathematics Project" is a problem-centered mathematics curriculum designed to help students in grades 6 to 8 develop mathematical knowledge, understanding, and skills. It contains eight student units for each grade level and covers five content strands: number and operations, geometry, measurement, data analysis and…

This paper shares the results of a study on the benefits which an experiential education program has on students in the K-12 range. The study was carried out at a bilingual North American-style college preparatory school located in Colombia, South America. Research was based on experiences obtained through the coordination and implementation of an…

The primary purpose of this study was to examine significant differences, if any, in student achievement in the area of math and science of students taught by traditionally certified teachers and alternatively certified teachers. This study examined alternatively certified teachers, as identified from through the Georgia TAPP (Teacher Alternative…

Organized around the ISLLC standards, this text introduces students to the concepts and theories of educational leadership. The new edition adds coverage of such topics as data usage, ethics, innovative hiring practices, and student discipline. Appearing in the second edition are chapter-ending sections called "Point-Counterpoint" which prompt…

The Association Supporting Computer Users in Education (ASCUE) is a group of people interested in small college computing issues. It is a blend of people from all over the country who use computers in their teaching, academic support, and administrative support functions. ASCUE has a strong tradition of bringing its members together to pool their…
